United States Patent | 5,741,343 |
Lloyd ,   et al. | April 21, 1998 |
Repositionable stacker bar pads composed of a relatively high-strength nonmetallic material have tongue-in-groove adjoining surfaces and glass-contact surfaces which are roughsned or serrated. The high strength material and overlapping tongue-in-groove "footprint" allows rigid and reliable attachment to a metal support structure. The rough finish of the glass-contact surface minimizes thermal checking and other hot-glass article problems.
